Usage notes

Used as an adjective (see below), ‘myriad’ requires neither an article before it nor a preposition after. Because of this, some consider the usage described in sense 2 above, where ‘myriad’ acts as part of a nominal (or noun) group (that is, “a myriad of animals”), to be tautological.

Quote of the night – “Sir, wait! the football meeting is in the room to your left!”

My reply, gesturing to the right side meeting area- “Thanks, but I’m going to knitting!”

In the night through the house it would aimlessly creep.

In spite of the fact of its being asleep.

From Edward Gorey’s The Doubtful Guest (1957).
